'certain new and useful Reinforced Fireproof Partition, ofiwliich the following is a specilAicatinn..

This inventionl is a reinforced reproof lo partition adapted to be easily and quickly 2.0 service of skilled workmen, and, to e constructed in buildings and other structures.` I The objects which I seek to accomplish are, first, to reduce the thickness of the par- -tition as compared with pnior devices; second, to increase the strength and stability l of the structure notwithstanding the aforesaid reduction -in the thickness thereof.; third, to enable the partition to be installed economically, and without requiring the ectually conceal the reinforcing means employed in the construction of the new partition;

The invention comprisesa relatively thin core which is reinforced by metallic stays and runiierathe whole being incased in suitable surface layers of plastic material, said `core being composed of the material known as plaster board. These plaster vboards are laid in courses, so as to be hound together 'I 30 -by verticaland horizontal lengths of metal which constitute the reinforcing bonds. Preferably, the horizontal lengths of metal are'interwoven with the vertical lengths so as to assumea zig za form in the partition,

- l.whereby the metallicbond is interwoven and made taut. Subsequently to the installation of the core land the metallic bond, surface layers of'plastic material, preferably plaster, are applredto the partition so as .4010 lill the spaces between the plaster boards and the lengths of the metal, whereby.the

, metallic reinforce is concealed within the 'surface finish of plastic material:

In the accompanying drawings, I have 45, illustrated one practical embodiment of the invention, but the construction shown therein is to be understood as illustrative only, 4and not as .defining the limits of the invention.

\ Figurefl is a perspective view showingy 150 the method .of installing my new reinforced partition. Fig. 2 is a horizontal section on the line -2-,2 of Fig. 3, said line-of section extendin through a part of a door jamb or frame. the line 3--3 of Fig; 2. Fig.` 4 is a detail l ig. 3 is a vertical cross section on g i are interwoven or interlaced so as to produce 4110 view showing a portion of one horizontal metallic runner,

In Fig. 1 of the drawings I have shown partitions forming two walls of a room or other. inclosure. The Hoor, A., and ceiling, B, are of any appropriate construction, either ireproof or otherwise, and the door frame or jamb, C, may, also, be of suitable construction. As shown in Fig. 2 a post. or column C', is at the corner or angle formed by the two partitions cr walls, said column being com, osed of a metallic flanged beam set in the 'ocr and ceiling, but it is evident that a wooden post may be employed.

Each i partition consists of a core, l), a metallic' bond to be presently described, and surface coatings, E, Ef, of plastic material.

The core, D, is composed, preferably, of the material known as plaster board for the reason that it is economical, fireproof,

l and readily installed. As is Well known,

plaster board consists .of sectionscoiposed of plastic material molded and dried inslabs which may bc'easily and quickly assembled. The plaster board is laid or installed in courses, indicated at, d, d", d2, d3; and it is preferred to set the sections onr edge, to impose them one upon theiother, and to assemble each section so its end edges will not coincide with th'e corresponding edges of other sections, or, in .other words, the sections willl break joints, see Fig. 1.

The metallic bond is shown by ,the drawings vas consisting of two rows of upright stays, F, F', and a plurality of horizontal' runners, G, each stay and runner being vcomposed of metal. It is preferred to employ yertically. The lower end of each stay. is

fixed .or anchored ,in a suitable way, at f, in

the floor, A, while the upper end of the 'stay is secured .or anchored, at f', in the ceiling,

B,- see Fig. 3.v The stays'are show n as. arranged in two series, on the respective sides ,of the core, D, although this `is optional for the reason that a single series may be used.

The horizontal, or substantially horizontal, runners, G, may each be composed of any suitable material, such as a wire, cable or rod: but as shown in the drawings each runner is composed of a substantially flat vmetallic hand. The runners and the stays l an lapproximately grille-like structure which g ner` heretofore described, after which'the servesvthe purpose of la nieta-llicbond or reinforce for the partition. Suitable means for connecting the runners and staysshould be provided, and asshown each runner has fan integral tongue, g, whichv is cut or stamped, as at g', in Fig. 4, from the metal vof the band or hoop, said tongue being foldable around one of the stays for the purpose ofl connecting the runner Aat each point of intersection with the-stays. The end portions of the runners are'anchored or secured l to the frame of the building, orto any other suitable.` rt thereof, 'such as the door jamb, C. Asfsliiwn in Fig.2 each runner, Gr, has an end fastened to the door jamb, C, asat g2, andtheserunners are arranged atv the horizontal joints between the courses, d, CZ', (Z2, al, of the plaster board core, D.

s a preferred construction, the horizontal runners, G, are interlaced with the'upright stays, F, F', so as to assume the zig zag form lshown in Figs. -1 and 2. Each runner is fastened at one end to the frame or door `jamb, C,-as at g2, thenlbent at, Ii, around one stay, F, then carried diagonally acrossthe core,-D, to the next stay, F', around which itis bent at, it', thence extended diagonally stay, F, around which it is bent at it, and so on throughout the series of stays, andthe .length of the partition. By bending the runners as described, they drfw the stays taut, and it is preferred to'bend'the stays so that they, also,l extend diagonally to and fro with respect to the core, D. The runnersl and are built around two or' more sides of a room,

and extended `diagonally across the plaster the runners, G, are looped around the corner 'post or column, C', and on the corner stays 'of the series F', as shown in Fig. 2.

The first step in the installation of a partition as contemplated by the preferred mode of procedure is to erect the stays, F, F', at the proper places, and fasten them to the bed or floor, A, and to the ceiling. I The rst course, d, of the plaster board is then placed in positioir between the stays, and then the lirst runner, G, is interlaced with the stays board, d. One end of said runner, G, is fastened, the runner is'stretched'so as to strain the stays, thereby making all the parts taut and drawing the stays across the 'plaster boa rd, the other end of the runner; is suitably fastened to a part of the building, and the tongues, g, are bent around the stays., 'The next course, d, of plaster' board is now placed in position and forced down between and upon the stays so as to engage, practically, with the zig zag rst runner, and the second runner, G, is now applied in the manf r r I f backward across the core, C, to the next v of the runners on the stays, `all operations lare repeated until the partition is built up. The linal step consists 'in apply ing the incasing material, E, E', 4to the re-4 spective surfaces of the partition. Said ma- Wall covering, and said plastic material may be applied in one or inorelayers as desired. rI'he plastic incasing material fills up the spaces and crevices in the plaster board, and' between the courses thereof, and bet-Ween and around' the stays and the runners, whereby are thoroughly covered and the layers, E, E', give a lroper finish to the partition. y

My new structure, andl thenovel method of'inst-alling the same herein described, is characterized' by a remarkable degree of vstrengthl in the partition, owing to the fact that the metal is interlaced and united with the core. The partition is Vnot as thick as ordinary structures, it is -thoroughly re`- quickly land without the labor of skilled workmen.

Having thus described my invention, n'lhat vI claim as new and desire to secure by Lettersl Patent is 1 .A 1 In a device of the class described, acore composed of i sections of plaster board im-l posed edgewise one upon the other,.a plurality vof series of vertical stays lstretched on the ,respective sides of the core, thestays `-of one series, metallic runners extending 's transversely through said core and interlaced with said stays, and plastic ymaterial incasing the stays andthe core.v j; i T
